Titan Usa CD44513 Jobber Drill Bit 13/64 Inch Hss

Product Description

The TITAN USA CD44513 is a 13/64 inch (0.2031 inch) high speed steel jobber drill bit designed for production and general-purpose drilling in metal fabrication and maintenance applications. It features a 135-degree split point that self-centers on contact, reducing walking and the need for a center punch on most surfaces. The two-flute spiral design with a regular helix promotes efficient chip evacuation during through-hole and blind-hole drilling. A black oxide coating provides mild lubricity and corrosion resistance during service. The overall length is 3.625 inches with a flute length of 2.4375 inches, making it suitable for standard jobber-length drilling tasks. This bit is installed and used by machinists, millwrights, pipefitters, and general maintenance trades.

The CD44513 is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is a straight-cylindrical shank bit compatible with standard 3-jaw drill chucks in handheld drills and drill presses. Typical applications include field drilling in HVAC fabrication, pipe fitting layout, electrical enclosure work, and general metal fab. The 12xD flute-to-diameter ratio supports moderate drilling depths up to 2.4375 inches. Coolant-through is not supported in this configuration.

Key Features

• 135-degree split point self-centers and reduces drill walking on metal surfaces
• High speed steel construction handles steel, stainless steel, cast iron, non-ferrous metals, and superalloys
• Black oxide finish provides mild lubricity and corrosion resistance
• Regular spiral, two-flute design promotes consistent chip evacuation
• Straight-cylindrical shank fits standard 3-jaw drill chucks
• Diameter tolerance of -0.0007 to +0.0000 inch for close-tolerance hole sizing

Compatibility

Designed as a standard jobber-length drill bit for use in any 3-jaw drill chuck that accepts a straight-cylindrical shank. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium (ISO material codes P, M, K, N, and S).

Installation Notes

Install the shank fully into a properly tightened drill chuck before operation, and confirm the bit runs true before cutting. Secure the workpiece with a vise or clamp — never hold metal by hand while drilling. Use appropriate cutting fluid or coolant when drilling stainless steel, superalloys, or titanium to extend tool life and prevent work hardening. Follow applicable shop safety practices and PPE requirements when operating drilling equipment.
